You were a girl studying at U.A., hated and feared by all. The reason? Your Quirk: Blood Art.
Your body possessed strength and speed far beyond that of any normal human, capable of crushing villains with a single blow and moving so fast you vanished before your enemy could react. You could freely manipulate your blood to create solid weapons: giant hammers, knives, spears, or scythes that you controlled remotely with lethal precision. You hardened your blood like steel and used it to attack or defend yourself, even storing it in jars like traps that exploded in a rain of crimson spears. In combat, you were a spectacle of destruction: you generated thousands of floating swords that hurled themselves like a red storm, laying waste to everything in their path. By drinking blood, your power and regeneration increased dramatically; more horns sprouted from your head, and your body became nearly indestructible. You could also transfer your own blood to heal others, though it consumed some of your life force.
You had long, straight, light blonde hair that reached your waist, with messy bangs that covered part of your forehead. Two short, sharp, red horns protruded from your head, contrasting sharply with your pale skin. Your intense red eyes always held a mocking and defiant look. You wore a wrinkled, half-unbuttoned white shirt with a loose black tie and a large blue jacket that draped over your shoulders. Your black pants reached mid-calf, and you wore white sneakers with red details and orange laces.
That's why everyone feared you: your classmates, the other students, and even some teachers. Nezu and All Might themselves preferred to keep their distance. Your attitude didn't help either; you were impulsive, childish, and selfish, always acting on instinct and for pleasure. You loved to show off, to feel superior, and to fight just for fun, though you'd run away without hesitation if things got tough. You lied without thinking, blamed others for your mistakes, and did whatever suited you, disregarding authority. Messy, gluttonous, and careless, you hated vegetables and loved blood more than anything.
Even so, loneliness never weighed you down. You saw people as weak, disgusting beings who didn't deserve to live. To you, villains only did the work others didn't dare to do.
One night you simply vanished. No goodbyes. No looking back. You knew no one would notice your absence. And although you felt a slight emptiness in your chest, you also felt relief: you were finally free.
You embraced a quiet life, moving through crowds without anyone recognizing you. Although you sometimes saved humans, you understood why you saved people if, deep down, you despised them.
One day you were walking through the busy streets, devouring a huge steak sandwich with hot sauce, washed down with an ice-cold beer. Some people looked at you with disgust at the way you were eating, but you didn't care; you kept chewing with a satisfied smile. Beside you, a small cat with white fur and black spots kept pace. It had slightly long fangs, bright yellow eyes, and an expression as haughty and cheeky as your own. You had found it in an alley weeks before, covered in blood and still with its claws sharpened. Instead of running away, it hissed at you… and from then on, it never left your side. You called it "Spark," although sometimes you just called it "annoying."
While you were eating, you felt a tap on your shoulder. You turned slowly… and saw them: Midoriya, Bakugo, Todoroki, Uraraka, Iida, Tsuyu, Mina, Kirishima, Momo, Denki, Jiro, Tokoyami, Sero, Shoji, Ojiro, Hagakure, Aoyama, Sato, Mineta, and Koda. All your old classmates.
They froze, surprised to see you after so long. You, on the other hand, showed no emotion whatsoever. You glared at them with a cold, murderous stare before taking another bite of your sandwich and a swig of your beer. Spark climbed onto your shoulder, remaining still as you watched your old classmates.
